Ip Tracking Technology And The Realization Of The Lan

The default of IP protocol results in network security. The most important problem regarding with IP protocol is the forged IP address. IP protocol cannot confirm that the source address is the sender's address.' A machine can forge itself as another machine even a router. In the various methods dealing with network attack, IP traceback emphasize on punishment. Once an attacker knows an attack can be tracebacked, the default of IP protocol and operation system results in network security.

Once an attacker knows an attack can be tracebacked, he will be discreet. In the developed countries such as America and Japan, IP traceback becomes the hot problem attended by governments, industries and academe. he will be discreet. In the developed countries such as America and Japan, IP traceback becomes the hot problem attended by governments, industries and academe.The mainly contributions of this paper include these following three aspects:(1) This paper discusses the DoS attacking principle, attacking taxonomy and attacking modes.(2) This paper discusses some IP traceback modes,algorithm and mechanism.(3) We propose a SNMP-based technique for reconstructing the attack path in origin network.
